Three distinct nitric oxide synthase genes are expressed in the cerebr
al arterial wall. Constitutive isoforms are localized in endothelium a
nd perivascular nerves, whereas only inducible enzyme is present in sm
ooth muscle cells, demonstrating the complex role of nitric oxide in r
egulation of cerebral arterial tone.
